Explain with details how does the pathogen invades our tissues and body after transmission. You need to include any receptors, steps etc. in its life cycle and/or the type of replication or reproduction it exhibits and how and where it exits the cells, tissues, or body. This section can also include how it spreads through the body if that is relevant.arrow_forwardIn 1985 a Paterson, N.J., Fire Department ambulance responded to a call reporting two people with severe itching, which they attributed to "voodoo beans" found in their beds. Soon after arriving the ambulance medical technicians developed the same symptoms. All four of the individuals went to the emergency room where they were found to have rashes on various parts of the body in addition to their itch. The admitting nurse, who put her arm around one patient, also developed a rash and itch on her arm. A policeman who went to the apartment the following day and a trash collector at the building also developed itching and received emergency room treatment. In all cases, symptoms disappeared in 1-2 hours. An industrial hygienist went to the site in complete protective gear to look for possible chemical contamination. Visual inspection and screens for ionized organic vapors were negative, but he retrieved a bean pod. The botanical specimen was sent to Rutgers University, where the plant was…arrow_forward
- One of the most characteristic symptoms of malaria is the alternation of attacks (involving a cold phase, a hot phase, and a sweating phase) with periods of 1 or 2 days of no or few fevers. Given the life cycle of Plasmodium what is the best explanation for this pattern: When free in the blood, merozoites release chemicals that directly cause body responses. Merozoites appear in coordinated “waves”, which explains the cycling attacks Merozoites entering the red blood cells generate a strong response from the red blood cells, which stimulates a massive immune response Attack phase correlates with simultaneous bursting of infected red blood cells, releasing thousands or millions of merozoites. This triggers massive immune response, resulting in symptoms Plasmodium generates a constant accumulation of irritants in the blood, mostly residues from digesting hemoglobin . Once the amount reaches a critical level, these trigger a massive immune responsearrow_forwardWhat the linked video below and answer the questions below https://youtu.be/z3k3GZ1F_rg 1) Describe a burr cell?
